Hey my wife was afraid of a loud ricer exhaust and she approves of this set up for the axle backs....as for the full catback system we shall see feb 1st on how she likes it after that also they are planning on doing the down pipe also! I don't see a low rumble during acceleration and during cruzing speeds it literally is barely noticeable! I will try and get a video of the exhaust after the car warms up during a drive around town!!
